1.0 INTRODUCTION 1.1 Purpose The purpose of this policy is to prevent any fires that may result from Hot Work processes. This plan is to be used by properties within the five boroughs of New York City only. 1.2 Scope 1.2.1 For the purposes of this policy, Hot Work is defined as any temporary operation involving open flames or producing heat and/or sparks. This includes, but is not limited to, grinding; cutting, brazing, soldering; all torch operations; torch applied roofing, and electric arc welding 1.2.2 This policy applies to all personnel (including contractors) who are involved with construction and maintenance activities and/or who may be involved in Hot Work activities on any SL Green managed or operated property. 1.2.3 No Hot Work will be permitted during hours of normal building occupancy from 8AM-6PM Monday through Friday. Such work must be done during overtime hours. 2.0 RESPONSIBILITIES 2.1 Building Office The ultimate responsibility and authority for compliance with this hot work permit program rests with the Building Office. It is their responsibility to ensure that the hot work permit program is carried out within the property. 2.2 Building Personnel Property Managers, FSD and Chief Engineers Individuals who have supervisory responsibility play a key role in the hot work permit program. It is their responsibility to ensure that: 2.2.1 Individuals working under their direction are trained and understand the applicable provisions of the hot work program and that all requirements of any hot work permit is fulfilled before work is performed. 2.2.2 An approved Hot Work Permit is obtained from: a. the Building Manager for any hot work conducted on property, or b. the Fire Safety Director for any hot work conducted on property, or c. the Chief Engineer for any hot work conducted on property. 2.2.3 Properly trained fire watches are assigned when required by the Hot Work Permit. 2.2.4 Designated areas are established for welding, cutting, brazing, torch soldering and grinding operations where a potential for fire danger exists. 2.2.5 Employees performing hot work (and their supervisors) are required to be suitably trained in the safe operation of the equipment. 2.2.6 All contractors are advised about flammable materials or hazardous conditions of which they may not be aware in areas where they will be working.

2.2.7 Outside contractors and service personnel are informed of the expectation that they will follow all OSHA requirements, including obtaining a hot work permit, if applicable to the job being performed. 2.2.8 Outside contractors have a verified Hot Work Permit if one is required for the work being conducted. 2.3 Individuals Performing Hot Work Work with torches must be done in well-ventilated areas only. Fans or smoke eating devices may be used to forcefully ventilate an area. Work with torches may never be done next to explosive and/or flammable materials. Torches must not be used in areas where flammable or hazardous vapors are present. Possible sources of flammable vapors should be removed from the work area. The flammable vapors are easily ignited and may cause an explosion. When in use, the gas cylinders must be secured in an upright position. This is especially important for the acetylene cylinders. The acetylene cylinders have a special safety device installed to prevent explosions. This device will only work when the cylinder is in the upright position. The cylinders must be located at a safe distance from the torch operations. It is extremely important that the cylinders are not exposed to any oil or grease. The oil and grease can cause an explosion when mixed with oxygen under pressure. These explosions may cause serious injury and damage. Individuals performing hot work are responsible for: 2.3.1 Obtaining written approval from the Building Office, Fire Safety Director or Chief Engineer for the hot work to be conducted on property. 2.3.2 Ensuring that conditions are safe and hazard free before commencing the hot work. 2.3.3 Being prepared to contact their supervisors should conditions change or warrant reassessment during the hot work project. 2.3.4 Using appropriate personal protective equipment (PPE) while performing hot work (welding helmets, gloves, jackets, etc.). 2.3.5 Comply with all regulations having jurisdiction including OHSA, Federal, State and NYC. 2.3.6 Complete the appropriate section(s) of the hot work permit. 2.3.7 Care must be taken to make sure that sparks and pieces of hot metal do not cause a fire. 2.3.8 All torch operators must hold a FDNY Certificate of Fitness. Torch Use of Flammable Gases for Cutting and Welding (G-60). They must have this certificate in their possession during all torch operations. 2.3.9 Returning the completed hot work permit to the Building Office

2.4 Fire Watch is responsible for: At least one fire guard is required for each torch operator. The fire guard must observe the torch operations to make sure that stray sparks do not cause a fire. The fire guard must extinguish all stray sparks immediately. A second fire guard is required when the torch is used in a multilevel building. The second fire guard must be positioned on the floor below the torch operations and extinguish any stray sparks that fall to that floor. The fire guards must concentrate in on preventing fires. They may not be assigned any other duty while acting as a fire guard. The fire guard must remove all combustible materials located within 35 feet of the torch operations. When this is not possible the combustible materials must be covered with a protective shield. The shield must be fire resistant. When a major fire is discovered the fire guard must contact the Fire Department immediately. The Fire Department may be reached by dialing 911. The Fire Watch is responsible for: 2.4.1 Being aware of the inherent hazards involved in the hot work. 2.4.2 Ensuring that safe conditions are maintained during the hot work. 2.4.3 Ensuring that appropriate fire extinguishers are readily available. 2.4.4 Being properly trained on the use of provided fire extinguishers 2.4.5 Knowing how to report a fire or other emergency situation. 2.4.6 Extinguish small fires and all stray sparks immediately 2.4.7 Knowing how to properly report a fire 2.4.8 After the torch operations are completed the fire guard must make two inspections of the work area. The first inspection must be made 30 minutes after the torch was last used. The second inspection must be made 30 minutes after the first inspection. Both inspections are conducted to detect any smoldering fires. If a small fire is discovered it must be extinguished by the fire guard. 2.4.9 Using the appropriate PPE. 2.4.10 The fire guard must keep a detailed inspection log. This log must record the names and signatures of the fire guards, the dates, and the number of inspections conducted. The log must also include any fires that were discovered.
